Summary Introduction
To explain: The groups of vertebrates that were present during mass extinction event and those vertebrates that evolved afterward.
Concept introduction: The extinction is the phenomenon where the entire species dies with no surviving progeny. “The Great Dying” is the period where mass extinction of species occurred at the border between Paleozoic and Mesozoic eras. Several factors are said to have contributed to it namely severe volcanic activity, asteroid hitting the earth, and spontaneous release of carbon dioxide from sea floor deposits. After this severe extinction, a major natural selection occurred and a large set of species evolved to adapt to the new conditions.

Match each mass extinction event to its description. 1. Permian extinction 2. Cretaceous-Tertiary extinction 3. Triassic extinction 4. Devonian extinction 5. Ordovician extinction a. This extinction was most likely due to a change in sea level. During this event, about 60% of all marine species were eliminated. b. This is the best-known mass extinction. It eliminated most large animals, including the dinosaurs. c. This was the most severe extinction event. About 96% of life on Earth died during this event. d. This extinction was most likely caused by climate change. About 80% of land animals died during this event. e. This extinction was most likely due to a change in sea level. It especially affected coral reefs.arrow_forward
- Transitional species are species important in helping scientists determine the evolutionary path that species have taken over long periods of time. Lobe-finned fishes are the ancestors of amphibians and have fossils that are found in rocks that are at least 380 million years old. Fossils of the oldest amphibian-like vertebrate animals with true legs and lungs are found in rocks that are approximately 363 million years old. Paleontologists have found a sample of rock that is approximately 370 million years old which contains what seems to be a link between lobe-finned fishes and amphibians. Which of the following is a characteristic that you would not expect to see in this transitional fossil? Question options: Skeletal structures that indicate the development of legs. An intermediate structure between lungs and gills. Teeth that are intermediate to the lobe-finned fishes and amphibians. A neck that is more flexible than lobe-finned fishes.arrow_forwardplease see attachedarrow_forwardThe “age of fishes”, which began with the Cambrian Period (about 541 million years ago), and ended with the Permian/Triassic extinction event (about 252 million years ago), is also known as: the Mesozoic Era the “age of birds and mammals” the Cenozoic Era the “age of reptiles” the Paleozoic Eraarrow_forward

- It is known that it takes very long periods of time for new species to develop, and yet the fossil record for many organisms is characterized by long periods of Stasis (no change) followed by short bursts of intense Speciation (the disappearance of one species followed by the appearance of a new species). Thus in the fossil record, organisms seem to stay the same for long periods of time followed by a “sudden” change in the organisms (sudden with respect to evolution and geology). In other words, it appears that new species evolve suddenly as opposed to over long periods of time. The Theory of Punctuated Equilibrium helps to explain these seemingly contradictory occurrences in the fossil record. Discuss how Punctuated Equilibrium works (think about small offshoot populations that break off from the main population) and how it can explain the fossil record evidence. (Be sure to include information about why fossils of the offshoot population would be rare.)arrow_forwardDescribe a scientific hypothesis to explain the mass extinction of dinosaurs and many other organisms at the end of the Cretaceous Period.arrow_forwardAll of the following have been suggested as triggers for the Cambrian radiation of complex metazoans except: perhaps the Cambrian metazoans outcompeted the Ediacaran metazoans, opening up new ecological niches to fill perhaps a series of fortuitsus genetic changes provided more raw material for natural selection to act upon perhaps increased oxygen in the world ocean promoted the evolution of complex body forms perhaps the rise in sea level that flooded the margins of the continents during the earliest Paleozoic created abundant new ecological niches, promoting biodiversity O perhaps the "arms race" between predator and prey spurred evolutionary innovationarrow_forward
